To all whom, it ma; concern.

Be it known t at I, Gaosoa P. Knees- BURY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical Machines, of which; the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical inachines, such as linotype machines of the eneral organization represented in Letters atent of the United States, No, 436,532, to O. Mergenthaler, wherein circulating mat rices are released from a magazine or magazines in the order in which their characters are to appear. in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter raised b the second elevator and delivered to the i tributing mechanism from which thcyqpass' to the magazine from which they started.

' variations may be made therein, and in its Y 40 More particularly, it relates. to means whereby the abnormal operation of the second-elevator, such as its arrest in its uppernuost position, effects the immediate stoppage of the machine. The purposes and ad- .vantages of this arrangement will hereafter more fully appear from the detail descriplion thereof.

In the accompanying drawings, 1 have shown my invention in preferred form and by .way of example, and as applied to a linotype machine, but many changes and mode of application, which will still be comprised within its spirit. Generally speak- .ing, I desire it to bennderstood that I do notlimit myself to any specific form or embodiment, except in so far as such limita- .tions are specified in the claims.

Referring to the drawings: Figure l is a rear skeleton elevation of certain parts of a linotype machine embodying my invention;

. Fig. 2- is a sectional detail of the elevator mam, stop device. etc; and Fig.3 a plan thereof, partly in section.

As illustrated inthe Mergenthaler patent previously referred to, or as is customary in the somewhat modified commercial linotype machine, after the slug is cast, and the first elevator rises to its uppermost position, the line of matrices and spacers is transferred therefrom by' the slide G into the upper transfer channel (not shown), where the matrices engage with the second'elevator bar A. The bar A carried by the arm B provided with an arm and roller C located in suitable ated by the cam D, whereby the bar is moved upwardly into registration with the distrihuter box A to which the matrices are shifted in the ordinary way by the slide A. The s ,acer hook (shown by dotted lines in Fig. is operatively connected to the slide G, in such manner that when the slide moves the line into the transfer channel, the hook advances and engages the spacers remaining therein, and by its return movement restores them to the spacer magazine. The slide G is held in its retracted or inoperative poposition to be engaged and actusition by the pivoted pawl or detent J. In

normal operation, the detent is tripped to release the slide vby the contact therewith of an abutment 13 connected to the elevator arm B, in such manner that when the latter descends into operative relation to the intermedlate channel, the slide is permitted to operate. The parts so far described are or may be of any. usual or preferred construction, and except as hereinafter specified, -constitu te part of my present invention.

The means for actuating the slide G and the spacer hook are somewhat similar to those presented in Letters Patent 'of the United States to O; Mergenthaler, No.-

. powerful spring (i and are returned to normal position by the action of the cam- H upon the arm G all in the ordinary way. The cam is so formed that when the spring .3" acts to shift the slide (1: inwardly, its movement is controlled and uniform, which is necessary to secure the proper transfer of the matrices to the elevator bar A, as a sudden or jerky action would project them violentlyend spill them into the machine.

It sometimes happens in use that the elevator bar prevented from descending'at r10 the proper time, as for instance when due to the arrest of the distributor, the matrices are not "properly transferred to the alistril'iuter box and a i am occurs which holds the elevator in its uppermost position. \Vhen this happens, it is ordinarily necessary for the operator to leave his place at the keyboard and pass to the rear of the machine, in order to correct the dilliculty and clear theparts. At this time, the slide (l is held in its out ward or inoperative position against the force of the spring-G" by the deteut J, although the cam H has continued to move and has passed out of contact with the arm G When new the second elevator freed and permitted to descend, it trips the detent J and releases the slide G, which shoots for ward with great rapidity. because it is no longer under the control of the cam, and projects the line in front of it with excessive violence and frequently with disastrous results. This condition subjects the operator to great inconvenience, and chiefly be cause it hasheen dillicult in actual practice to control the slide sinmltanemisly with the clearing-and lowering of the second elevator. Various efforts have been made to obviate the objection, such, for instance as the provision of manually controllable devices at the rear of the machine, the provision o f a yielding abutment for the slide detenl, and the like. Tn the present instance, I have provided means whereby the almorinal operation of the elevator, such as the arrest of its descent. instantly effects the sto uiagc of the machine, and thus the continued inuvcment of the cams will be preventedwhen the elevator is aria-rated.

The elevator cam D and transfer cam H are. both mounted upon the cam shaft l which is actuated through gearing E and E from the power shaft F. Upon the end of the shaft F is loosely molmtcd the drum 0 to which power may he imparted in any suitable manner. Rigidlv connected to the end of the shaft l and within the drum 0, are the radiall movable clutch members l. which in their extended position engage the drum and effect the rotation of the shaft l and when retracted break. the actuating cugagcment. livotall v connected to the clutch members l. and to the end of the bolt mounted in a suitable bore in the end of the shaft l, are. the links P, the arrangement belng such that when the bolt (1 is ll'lUYMl inwardly the clutch is closed, and when moved. outwardly the clutch is opened. The l g S connected to the bolt tends to give the latter its operative position, at which time the shaft F and the cam shaft i i are continuously rotated. The stopping move ment of the holt Q is imparted thereto bv the clutch lever M provided at one eiflrcuiit v' with the fork N which acts upon the collar 2 secured to the bolt Q, and its other tremitv with suitable controlling eonnec' Lions It will thus be seen that when the lever M shifted to move the fork N inwardly, the spring 3 acts to close the clutch, and that when the lever is shifted in the opposite direction against the force of the spring S. the outward movement of the bolt (Q acting: through the links P opens the clutch. In thc arrangement illustrated, I have provided means acting upon the lever M. to shift it outwardly and thus arrest the rotation of the cam shaft E, if for any reason the descent of the second elevator be a "rested.

Referring to Figs. '2 and it will be seen that the elevator arm B and cam arm (I are mounted upon the rock shaft El; and that also connected thereto is a third arm L provided with a laterally projecting pin L adapted. to actuate a stop piecc or slide K under certain conditions. The piece K is movablv mounted upon the side of the cam ll. its arrangement being such that it is permitted to slide thereon to a certain limited extent, and it is provided at one end with a beveled portion K to cooperate with the pin L on the arm L. and at its other end with :1 depending arm K to engage a beveled memher M on a vertical bracket M mounted on the clutch lever M.

In the normal operation of the parts, ,as :hown by full lines in 2, the slide K is so locateal that its beveled portion K will z-lcar the pin ll upon the arm 1., and its arm hi will clear the beveled member M of the liraclcct hi this result arisin from the continued contact of the arm (7 with the cam l), "when the second elevator is descending in thc normal manner. rcason the dcsccnt of the second elevator is arrcsh ll. hr rotation of the shaft E carries ll i ai-tivc sur ace of the cam D away from and out of conluct with the arm C, as-sho'wn h dolled line in Fig. 2. the latter is held ;--latiouar r because of its connection to the chwator arm ll. in these circumstances the arm l) al o rcu'niins stationary and the pin ll slarals in the path of the beveled portion K of the slid K. as the latter is rotated by H owcver, if for any the cam ll. thicontact of the pin with the bevcl acting to move the slide K longitudinallv and its arm K into the path of the beveled member M on the bracket M. The further rotation of the cam II therefore effccls. through the action of the arm K on the-action of the spring G upon the slide G and the spacer hook is substantiall normal,

and violent action is entirely obviated. Moreover, there is no longer necessity for the previously proposed auxiliary safety devices, such as a yielding abutment on the second elevator, or the manually controlled devices at the rear of the machine. It is further pointedout that as soon as the elevator is cleared and the armC allowed to resume contact With the cam D, the pin L on the arm L will be moved out of the path of-the bevel K on the slide K, thus permitting the spring S to act, whereby not only is the clutch again closed, but the slide K is restored to normal position. In other words, the mere clearance of the elevator restores the parts to operative condition without further attention on the part of the operator.

- As previously stated, I have shown my invention only in preferred form and by way of example, and as applied to a linotype machine, but obviously many modifications and alterations therein, and in its mode of adaptatipn, will suggest themselves to those skilled in the art, without departure from its sco e.

aving thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

' 1. In a linotype machine, the combination with the second elevator, of means whereby the abnormal operation of said elevator will instantly effect the stoppage of the machine. 2. In a linotype machine, the combination with the rising and descending second elevator and its operating shaft, of means wherehy'th'e arrest of the elevator in its descent instantly effects the stoppage of the machine.

3. In a typographical machine, the combination of'a movable line transporter, a cam to control its movement, and automatic means for effecting the stoppage of the machine the instant the operative relation between said parts is'distnrbed.

4. In a typographical machine, the combination of the second elevator, driving mechanism comprising a clutch, devices for opening the clutch, and means whereby the arrest of the elevator will efi'ect the actuation of said devices.- and therefore the liability to their sudden I 5. In a typographical machine, the combination of a movable linetransporter, an element connected thereto, machine stop devices, and movable means for actuating said stop devices, the said means being controlled in their movement by their engagement with the element connected to the transporter.

6. In a typographical machine, the combi nation of a. movable line transporter, an slement connected thereto, driving mechanism comprising a clutch, a rotatable part operated by the driving mechanism, a member carried by the rotatable part and moved relatively thereto by its engagement with the element connected to the transporter, and devices whereby such relative movement of said member will e'fi ect the opening of the clutch.

7. In a linotype machine, the combimition of the transfer devices normally is ad against action, the second elevator Qilt'tpu'cE-Ci to release said transfer devices, a cam ta control the movement of said transfer devices when released, and automatic means to eii'ect the instantaneous stoppage ofthe ma.-- chine when the elevator is arrested; whereby the cam. is prevented from assuming a position where it ceases to control the movement of the transfer devices. 8. In a typographical machine, the combination of a movable line transporter, a re ceiving part, devices for transferring the line from the transporter to .the receiving part, and means whereby the improper transfer of the line by said devices immediately effects the stoppage of the machine.

9. In a linotype machine, the combination with the second elevator and the distributer box to which the line is transferred therefrom. of means whereby the incomplete transfer of the line will instantly cfi'ect the stoppage of the machine.

In testimony whereof, I have affixed my signature in presence of two witnesses.
